Killing of dogs is prohibited

Dear PAO,

Nana, our beloved dog, typically wanders around our lawn during his walks or when he needs a bathroom break. However, one day, he didn't return to our home. Despite reviewing our CCTV recording and initiating a search effort, several weeks have passed with no sign of Nana. We've diligently monitored our CCTV footage daily in hopes of finding clues about his whereabouts. Yesterday, we stumbled upon a disturbing clip showing our neighbor holding a dog resembling Nana. Shockingly, the neighbor proceeded to hang, burn, and butcher the dog for consumption. Did my neighbor violate any laws?
